Handsontable has support for merging table cells using the `mergeCells`
plugin but there was no support in Wagtail for storing which cells have
been merged or rendering them in the output template.
The client JavaScript will now save which cells have been merged and
the output template will merge or hide cells.
See https://handsontable.com/docs/6.2.0/Options.html#mergeCells
- Optimized/Customized/Catregorize -> Optimised/Customised/Categorise
- Github -> GitHub (80% were spelt with capital H, this is the way GitHub spells itself)
- GitPod -> Gitpod (most were without the capital P, Gitpod's site does not use capital P)
- Remove duplicate words (to to, the the)
- De-coupled -> decoupled
- implementors -> implementers (all other references used 'site implementers' so just aligning with the common case)
- Fix a/an usage in one case
- Fix one comment usage of ok, replace with OK
* Adding missing return statement to FormPage.process_form_submission in the "Custom form submission model" example to make it available to FormPage.render_landing_page, among other methods.
- Link to ModelAdmin showed incorrectly as `Index app` not `ModelAdmin app`
- Many code snippets were nested, causing double nesting to appear in published docs
Most of these are no longer applicable due to the introduction of Wagtail guide, where possible the new guide links are used now
- Re-add missing docs image for extending Draftail
- There is no Guide page (yet) for Inserting videos or images so those links have been removed
- Fix some additional reference issues where the page name and reference were causing issues
- fix some broken refs that were lost in the migration to markdown files
- use lower_snake_case for all internal refs (most follow this convention)
- release process sub-section in docs should be named release schedule instead
* Modified route decorator so it adds new route to view depending on pattern type; default to path
* Made a separate decorator
* Renamed route to path and updated RoutablePage models
* Added a check to warn user when using regex with path decorator
* Made @route alias of @re_path, added tests for @re_path
* resolves #7031
- apply general fixes to existing markdown documentation
- various cases of rst syntax still used
- update some links to be the new format
- clean up line breaks (prettier)
